Bitmap.createBitmap(Bitmap source, int x, int y, int width, int height) return wrong bitmap

I have to crop a bitmap image. For this, I am using

Bitmap bitmap = Bitmap.createBitmap(imgView.getWidth(),imgView.getHeight(), Bitmap.Config.RGB_565);
Bitmap result =Bitmap.createBitmap(bitmap,imgView.getLeft()+10, imgView.getTop()+50, imgView.getWidth()-20, imgView.getHeight()-100);
bitmap.recycle();
Canvas canvas = new Canvas(result);
imgView.draw(canvas);

But it cuts the bottom and right of the bitmap. Top and Left part of the bitmap exists in the output. That means x and y position has no effect.

I am searched for good documentation. But I couldn't.

Thanks in Advance

What is the problem here and how to solve?
